How to install a COLDER
1. Connect a compressed-air line with a COLDER. Prepare a nylon or urethane tube of
O. D. 8 mm x I.D. 5,5 mm (or bigger) for 190-75 SV / 185-65 SV and a tube of O.D. 6
mm x I. D. 4 mm (or bigger) for 160-65 SV/140-55 SV. Fit one end of the tube to the
connector of the COLDER firmly so that it will not come off. Fit the other end to
ensure by pulling the tube that they are fully connected.
The most suitable tube length is 2 m (or less) for 190-75 SV/185-65 SV and 1 m (or
less) for 160-65 SV/140-55 SV. If it is longer, COLDER may not perform properly
because the pressure of compressed-air supplied drops. When an air tubing is
connected with a COLDER, care is to be taken that couplings to be used should have
an inside diameter for the compressed-air passage of 5,5 mm minimum for 190-75
SV/185-65 SV and 4 mm minimum for 160-65 SV/140-55 SV. For connection of a
compressor and a dryer/filter, a bigger inside diameter is recommended.
2. Be sure to install a filter-separator on a compressed-air supply line.
3. If a dryer is not installed on the compressed-air line, a measure to prevent freezing
should be taken (See preventive measures against freezing given on the second page).
4. Install a COLDER in such a way that distance between the discharging outlet of cold
air and an object to be cooled is 20 mm to 30 mm and that the object is directly
exposed to cold air. If the distance is bigger, cold air required will not be obtained
because warmer ambient air will mix with the discharged cold air and the temperature
of cold air will rise.
